FUNCTION DESCRIPTION
System Interface
This chip has all three kinds of interface type with MPU : serial, 4-bit bus and 8-bit bus. Serial and bus(4-bit/8-bit)
are selected by IM input, and 4-bit bus and 8-bit bus are selected by DL bit in the instruction register. During read
or write operation, two 8-bit registers are used. one is data register (DR), the other is instruction register(IR). The
data register(DR) is used as temporary data storage place for being written into or read from
DDRAM/CGRAM/SEGRAM, target RAM is selected by RAM address setting instruction. Each internal operation,
reading from or writing into RAM, is done automatically. Hence, after MPU reads DR data, the data in the next
DDRAM/CGRAM/SEGRAM address is transferred into DR automatically. Also after MPU writes data to DR, the
data in DR is transferred into DDRAM/CGRAM/SEGRAM automatically. The Instruction register(IR) is used only
to store instruction code transferred from MPU. MPU cannot use it to read instruction data. To select register, use
RS/CS input pin in 4-bit/8-bit bus mode(IM = "High") or RS bit in serial mode(IM = "Low").
Table 2. Various Kinds of Operations according to RS and R/W Bits
RS R/W Operation
L L Instruction Write operation (MPU writes Instruction code into IR)
L H Read Busy flag(DB7) and address counter (DB0 – DB6)
H L Data Write operation (MPU writes data into DR)
H H Data Read operation (MPU reads data from DR)
Busy Flag (BF)
When BF = "High", it indicates that the internal operation is being processed. So during this time the next
instruction cannot be accepted. BF can be read, when RS = Low and R/W = High (Read Instruction Operation),
through DB7. Before executing the next instruction, be sure that BF is not High.
Display Data RAM (DDRAM)
DDRAM stores display data of maximum 80 × 8 bits (80 characters). DDRAM address is set in the address
counter (AC) as a hexadecimal number. (refer to Figure 1.)

In case of 1 line display with 5-dot font, the address range of DDRAM is 00H - 4FH (refer to Figure 2). When EXT
= "High", extension driver will be used. Figure 3 shows the example that 40 segment extension driver is added

Timing Generation Circuit
Timing generation circuit generates clock signals for the internal operations.
Address Counter (AC)
Address Counter(AC) stores DDRAM/CGRAM/SEGRAM address, transferred from IR. After writing into (reading
from) DDRAM/CGRAM/SEGRAM, AC is automatically increased (decreased) by 1. When RS = "Low" and R/W =
"High", AC can be read through DB0-DB6 ports.
Cursor/Blink Control Circuit
It controls cursor/blink ON/OFF and black/white inversion at cursor position.
LCD Driver Circuit
LCD Driver circuit has 34 common and 60 segment signals for LCD driving. Data from
SEGRAM/CGRAM/CGROM is transferred to 60-bit segment latch serially, which is then stored to a 60-bit shift
latch. When each com is selected by 34-bit common register, segment data also output through segment driver
from 100-bit segment latch. In case of 1-line display mode, COM0 - COM17 have a 1/17 duty ratio, and in 2-line
or 4-line mode, COM0-COM33 have a 1/33 duty ratio.

CGROM (Character Generator ROM)
CGROM has 5 × 8-dot 240 character pattern.
CGRAM (Character Generator RAM)
CGRAM has up to 5 × 8-dot 8 characters. By writing font data to CGRAM, user defined character can be used
(refer to Table 4).

NOTES:
1. When Be(Blink Enable bit) = "High", blink is controlled by B1 and B0 bit. In case of 5-dot font width, when B1 = "1",
enabled dots of P0 - P4 will blink, and when B1 = "0" and B0 = "1", enabled dots in P4 will blink, when B1 = "0" and
B0 = “0", blink will not happen.
In case of 6-dot font width, when B1 = "1", enabled dots of P0-P5 will blink, and
when B1 = "0" and B0 = "1", enabled dots of P5 will blink, when B1 = "0" and
B0 = "0", blink will not happen.
2. "X" : don't care

SEGRAM (Segment Icon RAM)
SEGRAM has segment control data and segment pattern data. During 1-line display mode, COM0(COM17)
makes the data of SEGRAM enable to display icons. When used in 2/4-line display mode COM0(COM33) does
that. Its higher 2-bits are blinking control data, and lower 6-bits are pattern data (refer to Table 5 and Figure 8).
